## anonymous 5 years ago what is 4 with exponent -1/2

1. anonymous

$4^{(-1/2)}$

2. anonymous

the negative in the exponent means that the expression can be in this form too: $1/(4^{1/2})$

3. anonymous

1/8

4. anonymous

so, you need to calculate 4^1/2 which the square root of 4

5. anonymous

1/2

6. anonymous

7. anonymous

sorry but what is the ^ mean?

8. anonymous

that is represents an exponential expression...so 4^(1/2).... is $4^{1/2}$

9. anonymous

which is related to multiplication and division

10. anonymous

the "^" is used when typing because it's usually difficult to do a superscript

11. anonymous

thx the carrot info makes sense. Unfortunately the exponent answer does not :(

4^-1/2 = ?

$4^{-1/2}=1/4^{1/2}=1/\sqrt{4}=\pm1/2$

15. anonymous

wow.

16. anonymous

um..........4 1/2..........???????

17. anonymous

nova, a fractional exponent means you're taking a root. an exponent of 1/2 means a square root. an exponent of 1/3 means a cubed root.

18. anonymous

sammy, 4 to the 1/2 power is same as square root of 4.

19. anonymous

oh............remember i'm only 10

20. anonymous

sweet! welcome aboard!

21. anonymous

The "^" symbol they used is shorthand for "exponents"

22. anonymous
